Abstract

In a data processing environment where multimedia presentations are played, users sometimes need to locate and select video frames from the presentation based upon the point in the presentation where certain text or audio is presented simultaneously with the video. For example, a movie advertiser or critic would like to be able to locate and extract a certain video frame associated with a certain audio segment or text string. A method is needed to allow the user to search a multimedia presentation for an audio or text predicate, whereby the search results list includes the video frames associated with the search predicate.

Method for Frame Selection from a Video Presentation through Synchronization
of a Predicate

      In a data processing environment where multimedia presentations
are played, users sometimes need to locate and select video frames
from the presentation based upon the point in the presentation where
certain text or audio is presented simultaneously with the video.
For example, a movie advertiser or critic would like to be able to
locate and extract a certain video frame associated with a certain
audio segment or text string.  A method is needed to allow the user
to search a multimedia presentation for an audio or text predicate,
whereby the search results list includes the video frames associated
with the search predicate.

      This system provides a convenient method for the user to search
a multimedia presentation with an audio or text predicate, and
capture the video frames which are associated with that predicate.
For example, a movie advertiser needs to extract a certain video
frame from a movie in order to use it as a snapshot for a magazine
article.  The critic wants a picture associated with the line, "Go
ahead.  Make my day." He/she enters or stripes this text (or voices
this audio segment) as a predicate for a multimedia search.  The
system automatically retrieves the 50 video frames, as a single
contiguous manipulable unit, which are synchronized with the data
matching the audio predicate.  These frames may then be played in
slow motion, including as...
